| Question | Answer |
|---|---|
| autotrophs | organisms that use energy from sunlight or from chemical bonds in inorganic substances to make organic compounds |
| photosynthesis | converts light energy from the sun into chemical energy in the form of organic compounds, primarly carbohydrates |
| heterotrophs | animals and other organisms that must get energy from good unstead of directly from sunlight or inorganic substances |
| light reactions | light energy (absorbed from the sun) is converted to chemical energy, which is temporarily stored in ATP and the energy carrier molecule NADPH. |
| Calvin Cycle | Organic compounds are formed using CO2 nad the chemical energy stored in ATP and NADPH |
| chloroplasts | organelles found in the cells of plants and algae; surrounded by a pair of membranes |
| thylakoids | inside the inner membrane of chloroplasts and are arranged as flattened sacs |
| grana | connects the thylakoids |
| stroma | surrounds the grana |
| pigments | compounds that absorb light |
| chlorophylls | a very important pigments |
| carotenoids | compounds found in the thylakoid membrane including yellow, orange, and brown |
| primary electron acceptor | the acceptor of the electrons lost from chlorophyll a is a moolecule in the thylakoid membrane |
| electron transport chain | the promary electron acceptor donates the electrons to the first of a series of molecules located in the thylakoid memrbane. These molecules are called ________. |
| chemiosmosis | the process through light reacts is the synthesis of ATP |
| carbon fixation | the incorporation of CO2 into organic molecules |
| stomata | small pores in plants |
